I bought a good running '93 K1100RS last May and have been bringing the bike back to its former stock self.
Photo day after purchase...

I discovered soon after buying it that the bike has been lowered about a inch and a half. To bring the bike back to stock, I replaced the shorter worn out rear mono shock with a stock one, and have changed the 17" five spoke rear rim back to a 18" three spoke. That change allows me to now get the bike on its centerstand. Another bonus...the speedometer and odometer now are just about spot-on with their function.

The main issue left now is the front suspension...checking and if need be, bringing it back to stock. I assume it's lowered a bit. The fork tubes appear to be at the top of the triple tree, so there's been no lowering there. The next place I guess to look is the length of the fork springs. Does anyone here have the stock length the springs should measure? I'm guessing if the front has been lowered that its been done with shorter springs.
Thanks for any help.
Randy

It's much more likely that they shortened the spacers, not the springs.

Stock springs (uncompressed): 16 13/16"

Stock spacers: 3 3/4"

I can get you the length of an uncompressed stock fork later.
